Let me break down the real reason why there is a 18/6 light cycle. Its actually very simple. Its the least amount of light needed to keep a plant in its veg state.
For this reason, many people use the 18 hrs light on 6 hours light off to save on the electric bill and save life on the bulbs.
Especially with HID bulbs. A agrosun metal halide bulb is pretty pricy and you save a 3rd of its life. What is amazing is that even though a plant will grow faster with 24 hrs of light, the energy saving 18/6 is very close to the same size. One of the reasons why is because roots continue to grow even during the dark period forcing the canopy to grow at a faster rate. LOL its a economic thing.
I have cloned with both 18/6 and 24/0 and I still can't prove that 24/0 is faster. Almost everybody I know will recommend cloning or rooting clones with 24/0 but I am not sure why, maybe its the american over do it mentality. I guess I should start taking better record to compare actual times roots develope in both light cycles, then we all can compare, its just gonna take a few grows.
